This is the Driving Ambition splitter/sealed undertray. It was Kip Olson's, now mine. How well does it work? When we installed it the first time, I did some high speed testing and discovered it was literally pulling itself down and pulling the mounting bolts out of my front bodywork. Thats what I call downforce. As I type this Shad is reconfiguring the attachment points to make it 'Rob proof'. Hopefully it will be ready in time for my track day this Friday at Infineon.
